About Water Balance



Water Balance was founded by Tom Reynolds to assist farmers and urban landscapers at the Ag-Urban Interface AND BEYOND optimize plant health, soil nutrient balance and irrigation management with proven, efficient and cost-effective solutions.

Tom entered the agricultural arena in the late 1970's and in Arizona where cotton, citrus, and cattle productivity had peaked (area, not yield). Soon, environmental aspects of water, soil, and air pollution were making all the agricultural news headlines. Molecular biology and chemistry were mature, and personal computing technologies, first in farm accountancy, along with radio technologies, were moving onto Arizona farms. Tom started using computers in 1973 as an employee at a construction company, By 1979 he held his B.S. degree in Ag-Industry_Crop Production and was employed collecting and reporting soil, water and crop data over a three-county service area in central Arizona. From sunrise to 1:00 PM data and samples were collected and recorded. By 4:00 PM, using a computer program written by E. Ray Bigler, CPAg, we had processed the data, printed the graphs, and started transmitting these reports to our several clients for their irrigation and nitrogen scheduling the next day or week.

As an early service provider to farmers and ranchers, Tom's Water Balance business model is built upon four pillars (see home page).  Tom has witnessed California agricultural producers remaining economically successful while also tending to their environmental impacts, which help keep their over-allocated watershed's fauna and flora in at least some degrees of health. Gone are the days of groundwater mining, unreasonable nitrogen losses to acquifers by non-uniform irrigation application, and unchecked air pollution. What Water Balance provides to farmers and ranchers enables them to invest in irrigation systems that reduce costs, reduce deliterious environmental impacts, nurtures watersheds, while improving water and nitrogen use efficiencies with much better certainty. Irrigation efficiency in wheat, citrus, cotton, and hay below 85% is no longer a 21st Century prerogative. Furthermore, producers in a position of precision irrigation and fertigation can go even further, beyond 90% efficiency, to maintain average farm gross incomes at what Dr. English at Oregon State University refers to as optimal irrigation management and deficit irrigation.  Only precision irrigation system design, crop feedback systems, precision water measurement/budgeting, crop production analysis, and the resources and commitment from owners create the space managers need to go there, tightening their belts with acceptable levels of uncertainty.

Tom received his Master's in Science in Agribusiness in 1989 from Arizona State University. Farmers in Maricopa and Pinal Counties were just facing water use regulations. Tom's Master's Thesis, "Can Growers Live Within the Law" provides substantial basis for his argument that scientific irrigation scheduling significantly (95% confidence) increases yield. Increasing yield without increasing water application volume translates to higher water use efficiency.

"Thomas Reynolds has provided high quality irrigation design services that meet NRCS standards and specifications. He has endured challenges that come with design changes in irrigation design requirements, and is persistent in making the recommended design changes in a timely manner."
